CVE-2020-7037Network attack vector

Authenticated file read via unrestricted XML entities

Published Apr 28, 2021 · Updated Sep 16, 2024

XXE in the Media Server of Avaya Meetings Server 9.x through 9.1.10 allows remote authenticated users to read system files. The screen-sharing API endpoint accepts XML, and its parser resolves attacker-defined external entities instead of disabling them. Access to that endpoint requires authentication; crafted XML can also make server-side requests or interrupt the Media Server.
